背景技术Background technique

随着对电信的需求的增加，光纤网络正在扩展到越来越多的区域。在各种设施例如多用户居住单元、公寓、私有公寓式住房、商业设施等等，光纤盒被用于提供光纤网络的用户接入点。这些光纤盒通过连接着网络集线器的用户缆线连接至光纤网络。然而，光纤盒和网络集线器之间所需的用户缆线长度基于光纤盒相对于网络集线器的定位而改变。结果，需要有一种光纤盒，其能够有效地管理用户缆线的长度改变。As the demand for telecommunications increases, fiber optic networks are being extended to more and more areas. In a variety of facilities such as multi-tenant living units, condominiums, condominiums, commercial establishments, etc., fiber optic boxes are used to provide customer access points to fiber optic networks. These fiber optic boxes are connected to the fiber optic network through customer cables connected to the network hub. However, the length of customer cable required between the fiber optic cabinet and the network hub varies based on the positioning of the fiber optic cabinet relative to the network hub. As a result, there is a need for a fiber optic enclosure that can effectively manage changes in length of customer cables.

Thebobbin 89 includes a first axial end portion 91 , an oppositely disposed second axial end portion 93 , and a coil portion 95 disposed between the first and second axial end portions 91 , 93 . The first axial end 91 is in rigid engagement with therear side 75 of thebase 31 . In the embodiment discussed, the positive engagement between the base 31 and the first axial end 91 of thebobbin 89 is achieved by a plurality of fasteners 97 (eg, bolts, screws, rivets, etc.). In a preferred embodiment, the fastener 97 is sunk into the first axial end 91 so as not to interfere with the payout of theuser cable 22 . Fastener 97 extends through first axial end 91 ofbobbin 89 and through mounting hole 87 in panel 71 so that whenbase 31 andend block 29 are in the closed position, the end of the fastener is disposed Within theinterior region 83 of thehousing 25 . In the embodiment discussed, a stop 99 (shown in FIG. 6 ), such as a nut, rivet head, cotter pin, or the like, retains the fastener 97 in the mounting hole 87, thereby rigidly retaining thebobbin 89.

In another embodiment, the outer diameter of the first and second axial ends 91 , 93 of thebobbin 89 is less than the height H of thefiber optic cassette 21 .

在所讨论的实施方式中，绕线管89限定出延伸穿过第一和第二轴向端部91、93的轴向孔101。轴向孔101被配置成接收具有中心轴线105的转轴103。转轴103包含安装板107，其具有多个安装部109，用于将安装板107安装至墙壁。随着绕线管89连接在壳体25上，绕线管89的轴向孔101和转轴103之间的接合允许绕线管89和光纤盒21的壳体25绕转轴103的中心轴线105一起转动。可以理解，本说明书和权利要求书中使用的术语″一起″在用来描述绕线管89和盒体28或盒体28的部件的转动时，指的是绕线管和盒体28彼此一致地转动。在优选实施方式中，轴承(例如，滚针轴承，球轴承，滚子轴承，滑动轴承，等等)布置在轴向孔101和转轴103之间。In the embodiment discussed, thebobbin 89 defines an axial bore 101 extending through the first and second axial ends 91 , 93 . Axial bore 101 is configured to receive a shaft 103 having a central axis 105 . The rotating shaft 103 includes a mounting plate 107 having a plurality of mounting portions 109 for mounting the mounting plate 107 to a wall. With thebobbin 89 attached to thehousing 25, the engagement between the axial bore 101 of thebobbin 89 and the shaft 103 allows thebobbin 89 and thehousing 25 of thecassette 21 to work together around the central axis 105 of the shaft 103. turn. It will be understood that the term "together" as used in this specification and claims, when used to describe the rotation of thebobbin 89 andbox body 28 or parts of thebox body 28, means that the bobbin andbox body 28 coincide with each other. turn around. In a preferred embodiment, a bearing (eg, a needle bearing, a ball bearing, a roller bearing, a sliding bearing, etc.) is arranged between the axial hole 101 and the rotating shaft 103 .

仍请参看图7，用户缆线22绕着绕线管89的卷绕部分95缠绕。为了保护用户缆线22免受因用户缆线22围绕卷绕部分95缠绕而导致的衰减，绕线管89的外周表面111的半径大于用户缆线22的最小弯曲半径。用户缆线22包含第一端部113(示于图6)，其穿过面板71中的缆线通道85(示于图6)，和第二端部115。如前所述，用户缆线22可以包含多根光纤。在所讨论的实施方式中，用户缆线22的第一端部113的多根光纤中的每个将具有连接器化末端，其与终端排59的后侧连接接合。用户缆线22的连接器化末端将被配置成与第二缆线23的连接器化末端(示于图1A)光学连接。然而，可以理解，这里公开的发明的范围并不局限于具有连接器化末端的第一端部113，因为用户缆线22的第一端部113的光纤可被拼接至多个具有连接器化末端的编线。在替代性实施方式中，第一端部113可通过布置在盒体28内的拼接连接部而光学连接至第二缆线23。Still referring to FIG. 7 , theuser cable 22 is wound around the winding portion 95 of thebobbin 89 . In order to protect theuser cable 22 from attenuation caused by theuser cable 22 being wound around the winding portion 95 , the radius of the outer peripheral surface 111 of thebobbin 89 is larger than the minimum bending radius of theuser cable 22 . Thecustomer cable 22 includes a first end 113 (shown in FIG. 6 ), which passes through the cable channel 85 in the panel 71 (shown in FIG. 6 ), and asecond end 115 . As previously mentioned,subscriber cable 22 may contain multiple optical fibers. In the embodiment discussed, each of the plurality of optical fibers of the first end 113 of thesubscriber cable 22 will have a connectorized end that engages the rear side connection of theterminal row 59 . The connectorized end of thesubscriber cable 22 will be configured to optically connect with the connectorized end of the second cable 23 (shown in FIG. 1A ). However, it is to be understood that the scope of the invention disclosed herein is not limited to the first end 113 having a connectorized end, as the optical fibers of the first end 113 of thesubscriber cable 22 may be spliced into a plurality of connectorized ends. of braided lines. In an alternative embodiment, the first end 113 may be optically connected to thesecond cable 23 by a splice connection disposed within thecase 28 .

用户缆线22的第二端部115被构造成实现与光纤配线集线器17的连续性。然而，如示于图1，设施13中的每个光纤盒21和光纤配线集线器17之间所需的用户缆线22的长度将随着每个光纤盒21相对于光纤配线集线器17的位置而变化。Thesecond end 115 of thesubscriber cable 22 is configured for continuity with the fiber optic distribution hub 17 . However, as shown in FIG. 1 , the length of the requiredsubscriber cable 22 between eachfiber optic box 21 in the facility 13 and the fiber distribution hub 17 will vary with the distance between eachfiber optic box 21 relative to the fiber distribution hub 17. vary by location.

下面将描述一种安装和使用光纤盒21以应对光纤盒21和光纤配线集线器17之间所需用户缆线22的可变长度的方法。光纤盒21提供双重功能，即用作用户缆线22的储存位置，并且选择性地放出期望长度的用户缆线22。A method of installing and using thefiber optic cassette 21 to accommodate the variable lengths ofsubscriber cables 22 required between thefiber optic cassette 21 and the fiber optic distribution hub 17 will now be described. Thefiber optic cassette 21 serves a dual function of serving as a storage location forcustomer cables 22 and selectively paying out desired lengths ofcustomer cables 22 .

通过将第一长度的用户缆线22围绕着绕线管89缠绕，第一长度的用户缆线22被储存在光纤盒21中。用户缆线22的第一长度包含安装长度，其足够长以便能够从盒体的安装部位28延伸至光纤配线集线器17，和额外长度，其为在安装长度已被放出后的用户缆线22保持在绕线管89上的长度。在一个实施方式中，第一长度大于或等于大约100英尺。在另一实施方式中，用户缆线22的第一长度大于或等于大约200英尺。在另一实施方式中，用户缆线22的第一长度大于或等于大约300英尺。在另一实施方式中，用户缆线22的第一长度大于或等于大约400英尺。在另一实施方式中，用户缆线22的第一长度大于或等于大约500英尺。在另一实施方式中，用户缆线22的第一长度的范围为大约100至大约2,000英尺。在另一实施方式中，用户缆线22的第一长度的范围为大约100至大约1,500英尺。在另一实施方式中，用户缆线22的第一长度的范围为大约500至大约1,500英尺。在优选实施方式中，绕着绕线管89缠绕的用户缆线22的第一长度的范围为100至500英尺。通过将绕线管89布置在壳体25的外表面上，壳体25的内部区域83可以非常紧凑，因为不需要在内部区域83中提供缆线存放区域。此外，同不带绕线管89的光纤盒相比，带有绕线管89的光纤盒21能为更大长度的用户缆线22提供更有效的缆线管理。The first length ofsubscriber cable 22 is stored in thefiber optic cassette 21 by winding the first length ofsubscriber cable 22 around thespool 89 . The first length ofcustomer cable 22 includes the installed length, which is long enough to be able to extend from the box's mountinglocation 28 to the fiber optic distribution hub 17, and an additional length, which is thecustomer cable 22 after the installed length has been paid out. Length maintained onbobbin 89. In one embodiment, the first length is greater than or equal to about 100 feet. In another embodiment, the first length ofsubscriber cable 22 is greater than or equal to about 200 feet. In another embodiment, the first length ofsubscriber cable 22 is greater than or equal to about 300 feet. In another embodiment, the first length ofsubscriber cable 22 is greater than or equal to about 400 feet. In another embodiment, the first length ofsubscriber cable 22 is greater than or equal to about 500 feet. In another embodiment, the first length of thesubscriber cable 22 ranges from about 100 to about 2,000 feet. In another embodiment, the first length of thesubscriber cable 22 ranges from about 100 to about 1,500 feet. In another embodiment, the first length of thesubscriber cable 22 ranges from about 500 to about 1,500 feet. In a preferred embodiment, the first length ofsubscriber cable 22 wrapped aroundspool 89 ranges from 100 to 500 feet. By arranging thespool 89 on the outer surface of thehousing 25 theinner area 83 of thehousing 25 can be very compact since there is no need to provide a cable storage area in theinner area 83 . Additionally, thefiber optic cassette 21 with thespool 89 can provide more efficient cable management for greater lengths ofcustomer cables 22 than a fiber optic cassette without thespool 89 .

在一个实施方式中，在用户缆线22的第一长度已被放出后，用户缆线22的第二长度或额外长度围绕着绕线管89储存。如果用户缆线22的第一长度大于用户缆线22的安装长度，则第二长度或额外长度围绕着绕线管89储存。In one embodiment, after the first length ofcustomer cable 22 has been paid out, a second or additional length ofcustomer cable 22 is stored aroundspool 89 . If the first length of thecustomer cable 22 is greater than the installed length of thecustomer cable 22 , a second or additional length is stored around thespool 89 .

光纤盒21的第二功能涉及用户缆线22的选择性放出。如前所述，用户缆线22的第一端部113与布置在壳体25的内部区域83中的第一端部59连接接合。在一个实施方式中，用户缆线22的第一端部113与适配器401连接接合。此外，即使是在用户缆线22的第一端部113和终端排59之间存在这种接合的情况下，用户缆线22仍能随着绕线管89和适配器绕一轴线彼此一致地转动而被放出，而不会中断第一端部113和适配器401之间的连接。如前所述，绕线管89与壳体25刚性接合，并且绕线管89的轴向孔101与转轴103接合，以使得绕线管89和壳体25能选择性地绕转轴103的中心轴线105转动。因此，在转轴103被安装至墙壁并且光纤盒21与转轴103接合的情况下，通过将光纤盒21沿旋转方向117(在图7中以虚线箭头表示)绕转轴103的中心轴线105转动，期望长度的用户缆线22可被从光纤盒21放出。由于壳体25和绕线管89一起绕转轴103的中心轴线105转动，因此用户缆线22的第二端部115可被放出，而用户缆线22的第一端部113不会被从终端排59拉出。一旦期望长度的用户缆线22已被放出，光纤盒21的转动停止。在这一点处，光纤盒21的位置可以固定，以使得其不相对于转轴103转动。在所讨论的实施方式中，销119穿过绕线管89的第二轴向端部93中的开口121，并且穿过安装板107中的相应开口123，以固定光纤盒21的位置。在优选实施方式中，当光纤盒21大体上水平时，光纤盒21被固定就位。A second function of thefiber optic cassette 21 involves the selective payout ofsubscriber cables 22 . As previously mentioned, the first end 113 of thesubscriber cable 22 is in connection engagement with thefirst end 59 disposed in theinterior region 83 of thehousing 25 . In one embodiment, the first end 113 of theuser cable 22 is connected to theadapter 401 . Furthermore, even with such engagement between the first end 113 of thecustomer cable 22 and theterminal block 59, thecustomer cable 22 can still rotate in unison with each other around an axis with thebobbin 89 and the adapter. and be released without interrupting the connection between the first end 113 and theadapter 401 . As before, thebobbin 89 is rigidly engaged with thehousing 25, and the axial bore 101 of thebobbin 89 is engaged with the shaft 103 so that thebobbin 89 and thehousing 25 can be selectively centered around the shaft 103. Axis 105 rotates. Thus, with the shaft 103 mounted to the wall and thecassette 21 engaged with the shaft 103, by rotating thecassette 21 about the central axis 105 of the shaft 103 in the direction of rotation 117 (indicated by a dashed arrow in FIG. 7 ), it is desired A length ofsubscriber cable 22 may be paid out from thefiber optic cabinet 21 . Since thehousing 25 and thebobbin 89 rotate together around the central axis 105 of the rotating shaft 103, thesecond end 115 of theuser cable 22 can be paid out without the first end 113 of theuser cable 22 being pulled out from the terminal.Row 59 is pulled out. Once the desired length ofsubscriber cable 22 has been paid out, rotation of thefiber optic cassette 21 is stopped. At this point, the position of thefiber optic cassette 21 may be fixed such that it does not rotate relative to the axis of rotation 103 . In the embodiment discussed, a pin 119 passes through an opening 121 in the second axial end 93 of thebobbin 89 and through a corresponding opening 123 in the mounting plate 107 to secure the position of thefiber optic cassette 21 . In a preferred embodiment, thefiber optic cassette 21 is secured in place when thefiber optic cassette 21 is substantially horizontal.

下面将描述从光纤盒21选择性地放出用户缆线22的替代性方法。在光纤盒21靠近光纤配线集线器17安置的情况下，用户缆线22的第二端部115被从绕线管89展开。在一个实施方式中，第二端部115被光学连接至光纤配线集线器17。在用户缆线22的第二端部115光学连接至光纤配线集线器17并且用户缆线22的第一端部113与终端排59连接接合的情况下，光纤盒21被传送离开光纤配线集线器17。在一个实施方式中，光纤盒21由安装工人从光纤配线集线器17带离。在另一实施方式中，光纤盒21通过轮式小车(例如，拖车、4轮推车，等等)从光纤配线集线器17带离。在优选实施方式中，光纤盒在传送过程中安置在封装盒体(例如，箱子)中。随着光纤盒21被从光纤配线集线器17传送，用户缆线22从绕线管89展开，引起绕线管89和壳体25在封装盒体中转动。当光纤盒21已被传送到其安装部位后，光纤盒21被从封装盒体取出，被安装到安装部位，并且固定就位。An alternative method of selectively paying out thesubscriber cables 22 from thefiber optic cassette 21 will be described below. With thefiber optic cassette 21 positioned adjacent to the fiber optic distribution hub 17 , thesecond end 115 of thecustomer cable 22 is unwound from thespool 89 . In one embodiment, thesecond end 115 is optically connected to the fiber optic distribution hub 17 . With thesecond end 115 of thesubscriber cable 22 optically connected to the fiber optic distribution hub 17 and the first end 113 of thesubscriber cable 22 engaged with theterminal block 59, thefiber optic cassette 21 is transported out of the fiber optic distribution hub 17. In one embodiment, thefiber optic cassette 21 is carried away from the fiber optic distribution hub 17 by the installer. In another embodiment, thefiber optic cassette 21 is carried away from the fiber optic distribution hub 17 by a wheeled dolly (eg, trailer, 4-wheel cart, etc.). In a preferred embodiment, the fiber optic cassette is housed in a packaging enclosure (eg, a box) during transport. As thefiber optic cassette 21 is conveyed from the fiber optic distribution hub 17, thecustomer cables 22 are unwound from thespool 89, causing thespool 89 andhousing 25 to rotate within the enclosure. After theoptical fiber cassette 21 has been delivered to its installation site, theoptical fiber cassette 21 is taken out from the packaging box body, installed in the installation site, and fixed in place.

现在参看图8和9，光纤盒221的替代性实施方式被示出。光纤盒221包含总体上以223表示的壳体，总体上以227表示的绕线管，总体上以229表示的轴承架(示于图9)，和总体上以231表示的安装板。Referring now to Figures 8 and 9, an alternative embodiment of afiber optic cassette 221 is shown.

总体上以241表示的终端模块布置在壳体223的内部区域239内。光纤盒221的终端模块241用作引入光纤和引出光纤之间的分界线。在所讨论的实施方式中，终端模块241被安装至壳体223的基部233。A terminal module, indicated generally at 241 , is arranged within theinterior region 239 of thehousing 223 . Theterminal block 241 of thefiber optic cassette 221 serves as a boundary between incoming and outgoing optical fibers. In the embodiment discussed, theterminal module 241 is mounted to thebase 233 of thehousing 223 .

在所讨论的实施方式中，终端模块241包含具有适配器槽245的适配器板243。适配器槽245被配置成接收多个适配器401(示于图3和4)。In the embodiment discussed, theterminal module 241 includes anadapter plate 243 having anadapter slot 245 .Adapter slot 245 is configured to receive a plurality of adapters 401 (shown in FIGS. 3 and 4 ).

现在参看图11，壳体223的基部233限定出缆线通道247，引入光纤穿过该缆线通道。壳体223的内部区域239包含放松储存区249，在其中布置着多个弯曲半径保护件251。每个弯曲半径保护件251的尺寸设置成使得弯曲半径保护件251的外侧半径大于光纤的最小弯曲半径，以避免光纤在储存过程中受到衰减损失。在所讨论的实施方式中，缆线通道247布置在放松储存区249和终端模块241之间。随着引入光纤穿过缆线通道247，引入光纤被引导至放松储存区249。然后，引入光纤的连接器化末端被从放松储存区249引导至适配器401的前侧413。引出光纤的连接器化末端被从适配器401的后侧引导并且穿过布置在第一和第二侧壁235、237中的光纤排出端口253。Referring now to FIG. 11 , thebase 233 of thehousing 223 defines acable channel 247 through which the incoming optical fiber passes. Theinterior region 239 of thehousing 223 contains aslack storage area 249 in which a plurality ofbend radius protectors 251 are disposed. The size of each bendingradius protection member 251 is set such that the outer radius of the bendingradius protection member 251 is larger than the minimum bending radius of the optical fiber, so as to avoid attenuation loss of the optical fiber during storage. In the embodiment discussed, thecable channel 247 is arranged between theslack storage area 249 and theterminal module 241 . As the incoming fiber passes through thecable channel 247 , the incoming fiber is directed to aslack storage area 249 .

However, as shown in FIG. 1 , the length ofsubscriber cable 22 required between eachfiber optic enclosure 221 in the facility 13 and the fiber distribution hub 17 will be based on the location of eachfiber optic enclosure 221 relative to the fiber distribution hub 17 And change.

下面将描述一种选择性地放出用户缆线22的方法。如前所述，用户缆线22的第一端部与布置在壳体223的内部区域239中的终端模块241连接接合。在用户缆线22的第一端部与适配器401的前侧413连接接合并且引出光纤从适配器401的后侧脱开的情况下，用户缆线22可被放出。如前所述，绕线管227的第一轴向端部255被刚性接合至壳体223，并且绕线管227的第二轴向端部257与轴承架229的第一板263接合，以使得绕线管227和壳体223能选择性地绕轴承架229的中心轴线269转动。因此，在轴承架229的第二板265被安装至安装板231，而安装板被安装至墙壁的情况下，通过沿旋转方向绕轴承架229的中心轴线269转动光纤盒21，期望长度的用户缆线22可被从光纤盒221放出。由于壳体223和绕线管227一起绕轴承架229的中心轴线269转动，因此用户缆线22的第二端部可被放出，而用户缆线22的第一端部不会被拉出终端模块241。一旦期望长度的用户缆线22已被放出，光纤盒221的转动停止。在这一点处，光纤盒221的位置可被固定，以使得其不相对于轴承架29转动。A method of selectively paying out thesubscriber cable 22 will be described below. As previously mentioned, the first end of thesubscriber cable 22 is in connection engagement with theterminal module 241 disposed in theinner region 239 of thehousing 223 . With the first end of thecustomer cable 22 connected to the front side 413 of theadapter 401 and the outgoing fiber is disengaged from the rear side of theadapter 401, thecustomer cable 22 can be paid out. As before, the firstaxial end 255 of thebobbin 227 is rigidly joined to thehousing 223 and the secondaxial end 257 of thebobbin 227 is engaged with thefirst plate 263 of thebearing bracket 229 to provide Thebobbin 227 and thehousing 223 can selectively rotate around thecentral axis 269 of thebearing frame 229 . Thus, with thesecond plate 265 of thebearing frame 229 mounted to the mountingplate 231 and the mounting plate mounted to the wall, by rotating thefiber optic cassette 21 in the direction of rotation about thecentral axis 269 of thebearing frame 229, a user of a desired length Thecable 22 can be paid out from thefiber optic cassette 221 . Since thehousing 223 and thespool 227 rotate together around thecentral axis 269 of thebearing frame 229, the second end of theuser cable 22 can be paid out without the first end of theuser cable 22 being pulled out of the terminal.Module 241. Once the desired length ofsubscriber cable 22 has been paid out, rotation of thefiber optic cassette 221 is stopped. At this point, the position of thefiber optic cassette 221 can be fixed such that it does not rotate relative to thebearing frame 29 .
